MARKlNG-BRUSHr 10 packagmmhich will hold a larger quantity of marking-liquid than an ordinary brush, and therefore will not require to be so frequently filled by dipping it into the said liquid, and which will work more uniformly-that is to say, will not vary in its operation like an ordinary brushaccording as it has been more or less recently filled,and contains a greater or less quantity of liquid.

The invention consistsof a brush-head made of one piece of soft vulcanized india-rubber or equivalent soft and elastic material, of hollow conical form, or of the form of two hollow truncated cones united at their bascs,and having openings in its'sides for the filling of the 5 reservoir constituted by its hollow interior and an opening at its tip for the issue of the liquid for marking. This head also has a socket or hollow neck, by which it will be attached to a stick or handlc,like that of an ordinary brush; and itmay have a flange made integral with it, for the purpose of keeping it raised up from and preventing it from soiling or rolling off from the table or other surface on which it may be laid when not in use.

Figure 1 of the drawings is a side view of a marking-brush constructed according to my invention. Fig. 2 is a central longitudinal section of the same parallel withFig. 2. Fig.

3 is an end view of the same. Fig. 4 is a transverse section of the same in the lines-r of 5 Fig. 6 is an end view corresponding with Fig. 5.

Similar letters of reference designate corresponding parts in all the figures.

A designates the brush-head, B its hollow socket, and 0 its flange, the whole made of a single piece of soft vulcanized india-rubher. The head A, as shown in Fig. 1, is in the form of two hollow conical frustums united Application filed March 23, 1887. Serial no. mom.

at the plane indicated by the line :0 x. lt has 'openings a a on opposite sides, extending a considerable portion of its length, and at its tip, which is somewhat flattened, there is anopening, b, consisting of a fine sht, which-- communicates with the hollow concave interior of the head itself, constituting the reservoir, and also communicates with the side openings, (1 a. This slit b is closed when the brush is not in use.

The example shown in Figs. 5 and 6 only differs from that shown in Figs. 1, 2, 3, and 4 in that instead of its having its tip flattened and with a slit like b it has its tip round,with a small hole, (1, in its center, as shown in Fig. 6 and by dotted outline in Fig. 5.

The brush-head of either of the above forms has a stock or handle, D, inserted into the socketor hollow neck, and it is to be used, like an ordinary brush, by dipping it into the liquid to he used for marking and afterward ing is afterward performed the pressure and variation of pressure produced on thesoft flexible tip by this act, and the free eirpansion and contraction of the whole head, which is also at the same time produced, cause a working out of the material through the slit or opening in the tip, and this will take place uniformly from the time when the brush has just been filled until the least drop remains in the reservoir.

hat I claim as my invention, and desire to secure by Letters Patent, is

1. A bruslrhead made-of one piece ofsoft iudia-rubber or equivalent soft elastic material, of hollow conical form, having openings in its sides, an opening in its tip, and an internal reservoir, substantially as hereindeseribed.

2. Thebrush-hjead made of one piece of soft india-rubber orequivalent soft elastic material, of the form of a hollow double cone, having openings initssidcs, an opening in its tip, and an internal reservoir, snbstantiallyas herein described.

3. The brush-head made of one piece of soft i ndia-rubber or equivalent soft elastic material,
